Dosage Instructions by QR Code: What It Solves

A printed carton has one language, set at print time. A QR code pointing at a page can show dosage and storage instructions in the patient's own language, and that page can be corrected or updated the moment guidance changes — without reprinting a single box already on a shelf.

What the page handles that print can't

• Language: the page can detect or let the patient choose their language; the carton can't.
• Updates: if dosage guidance changes, the existing page updates instantly — stock already on shelves stays correct automatically.
• Refills and reminders: the same page can offer a refill link and a reminder before the pack runs out.
• Recalls: patients who scan can be registered so they can be reached directly if guidance changes or a recall is issued.

None of this replaces the carton's own required labeling — it's a supplement reachable by a shopper who wants more detail than the physical label can carry, or who needs it in a language the carton doesn't print.

The same approach to labelling by QR code is used for ingredient information on wine and spirits — see EU e-label rules for wine and spirits.

Registering patients who scan works the same way as registering a purchase — see how to collect reviews from a product pack.
